+# Generating automatically a configuration screen
+
+{.alert.alert-info}
+**Important!** To generate a configuration screen automatically, you need to [import the "Scripting API Extra" script in your map](about.md#importing-the-extended-features)
+
+WorkAdventure comes with a ["variables"](https://workadventu.re/map-building/api-state.md) system that can be used
+to change a map dynamically. Variables can have an impact on a map through [property bindings](variable-to-property-binding.md),
+or through the [Scripting API](https://workadventu.re/map-building/api-state.md).
+
+In order to edit the value of a variable, the *Scripting API Extra* library comes with a way to define configuration
+pages automatically.
+
+The configuration page displays a form that is **generated from the variables** present on the map.
+Each variable is mapped to one field in the form.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/sample_configuration_screen.png" alt="" />
+    <figcaption class="figure-caption">A sample configuration screen</figcaption>
+</figure>
+
+For a variable to appear in the configuration form, it MUST be stored in a layer called `configuration`.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/variables_in_configuration_layer.png" alt="" />
+    <figcaption class="figure-caption">List of variables that will be displayed in the configuration screen</figcaption>
+</figure>
+
+## Protecting the configuration screen
+
+By default, the configuration screen will be accessible to anyone. You will probably want to restrict the access of the 
+configuration screen to users that have a certain *tag*.
+
+To do this, simply add a `tag` property to the configuration layer. The value of the property is the name of the tag
+that users must have to access the configuration screen.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_tag.png" alt="" />
+    <figcaption class="figure-caption">Here, only users with tag "admin" will have access to the configuration screen</figcaption>
+</figure>
+
+
+## Altering the display of a variable
+
+### Changing the label
+
+Each variable is mapped to one field in the form.
+
+By default, the name of the variable is used as the label.
+
+You can add a `label` property on the variable to display a custom label for your variable.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_label.png" alt="" />
+    <figcaption class="figure-caption">The label property added to a variable</figcaption>
+</figure>
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_label_screenshot.png" alt="" />
+    <figcaption class="figure-caption">The label property is used as field label</figcaption>
+</figure>
+
+### Changing the type of the field
+
+By default, a variable will be displayed as a text box, unless the `default` property is a boolean, in which case
+it will be displayed as a checkbox.
+
+You can alter this type of the field displayed by using the `type` **custom** property.
+
+{.alert.alert-warning}
+**Important!** The *type* of the point object  that represents the variable must always be `variable`. You should add
+a **custom** property whose name is "type" to set the type of the field.
+
+Acceptable values for the "type" property are:
+
+- `text`: displays a text field
+- `checkbox`: displays a checkbox
+- `select`: displays a select (see `allowed_values`)
+- `radio`: displays radio buttons (see `allowed_values`)
+
+### Enumerations (select / radio buttons)
+
+If you want to display a select box or radio buttons, you need to provide the list of possible values.
+This can be done through the `allowed_values` property.
+
+The `allowed_values` must be passed a JSON object whose keys are the text displayed, and whose values are the value that
+will take the variable if the option is selected.
+
+For instance, if you want to do a simple "Yes/No" radio button, you would write:
+
+`allowed_values: {
+    "Yes": true,
+    "No": false
+}`
+
+When you use the `allowed_values` property in your variable, do not forget to the the `type` property to `select` or `radio`.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_allowed_values.png" alt="" />
+    <figcaption class="figure-caption">The "allowed_values" property added to a variable</figcaption>
+</figure>
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_allowed_values_description.png" alt="" />
+    <figcaption class="figure-caption">The field is displayed as a "select" because we chose "type = select"</figcaption>
+</figure>
+
+
+### Adding a description / hint
+
+You can add a `description` property on the variable to display a description of the purpose of the field, below
+the field.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_description.png" alt="" />
+    <figcaption class="figure-caption">The description property added to a variable</figcaption>
+</figure>
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_description_screenshot.png" alt="" />
+    <figcaption class="figure-caption">The description property is displayed below the field</figcaption>
+</figure>
+
+### Field visibility
+
+The configuration page will respect the visibility rights configured on the variable.
+
+- If the `readableBy` property is set on the variable, the variable will appear in the configuration screen only if the current user has the right
+to read this variable.
+- If the `writableBy` property is set on the variable, the variable will be displayed, but modifiable only if the current user has the right
+to write to this variable. 
+
+## Creating sub-sections
+
+Do you have many variables on your map? You can organize these variables on different configuration pages.
+To do this, simply turn the `configuration` layer into a "group" layer. In this group layer, you can put many object
+layers. Each object layer will be rendered in a different page.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_layers_tree.png" alt="" />
+    <figcaption class="figure-caption">Variables are stored in layers inside the "configuration" group layer</figcaption>
+</figure>
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/configuration_main_page.png" alt="" />
+    <figcaption class="figure-caption">Each configuration page is accessible from the main page</figcaption>
+</figure>
+
+Each configuration page is accessible from the main page using a menu made of buttons.
+
+The label of the buttons can be edited by setting a custom `label` property on each object layer inside the "configuration" layer.

+# Binding variables to properties
+
+{.alert.alert-info}
+**Important!** To use variables to properties binding, you need to [import the "Scripting API Extra" script in your map](about.md#importing-the-extended-features)
+
+In WorkAdventure maps, ["variables"](https://workadventu.re/map-building/api-state.md) are used to share a state between 
+players.
+
+Using the Scripting API Extra library, you can bind your variables values directly into properties on your map.
+
+In a property of your map, use the `{{{ variableName }}}` to refer to the name of a property.
+
+**Sample**
+
+Let's imagine you want to dynamically change the URL of a co-website based on a variable value.
+You can create a new variable named "myWebsiteUrl" and bind it to the `openWebsite` property of your co-website layer.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/variable.png" alt="" />
+    <figcaption class="figure-caption">The variable</figcaption>
+</figure>
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/templated_property.png" alt="" />
+    <figcaption class="figure-caption">The property referring to the variable</figcaption>
+</figure>
+
+## Context
+
+You can use template properties in:
+
+- any property of any "tile" layer
+
+## Configuration
+
+Binding variables to properties can make your map reactive to variable changes, but you still need to find a way
+to modify the values of variables. There are plenty of ways to do this, including:
+
+- [Using the scripting API](https://workadventu.re/map-building/api-state.md)
+- [Using auto-generated configuration screen]() // TODO
+- [Using generic action zones](generic-action-zones.md)
+
+## About bindings
+
+Use `{{{ variableName }}}` to refer to a variable name.
+
+Behind the scene the [Mustache templating engine](https://en.wikipedia.org/wiki/Mustache_(template_system)) is used.
+This means you can use all the features of Mustache like conditional:
+
+`openWebsite: {{#enableWebsite}}https://example.com{{/enableWebsite}}`
+
+The website above will be displayed only if the `enableWebsite` variable is set to `true`.
+
+{.alert.alert-warning}
+Be sure to use `{{{ variableName }}}` for binding variable and NOT `{{ variableName }}`. The version with a double 
+curly-braces will work most of the time, but it escapes HTML characters (which is not needed in properties of a map)
+and this might cause weird behaviours (like breaking URLs)
+
+
+## The special "visible" property
+
+You can control the visibility of a layer with the `visible` **custom** property.
+
+If this custom property is set, it will override the "Visible" property of the layer.
+
+If you bind it to a variable, you can display or hide a layer based on the value of a variable.
+
+<figure class="figure">
+    <img class="figure-img img-fluid rounded" src="images/visible_property.png" alt="" />
+    <figcaption class="figure-caption">Usage of the `visible` property</figcaption>
+</figure>
+
+### Inverting a boolean variable
+
+In the example above, the `holeInWall` property is a boolean variable. If it is set to `true`, we want to hide the
+layer. So we are setting a `visible` property on the layer. If we put `visible: {{{ holeInWall }}}` the layer
+would be visible when `holeInWall` is `true`. But here, we want the opposite: the layer must be displayed when 
+`holeInWall` variable is `false`. To do this, we can use Mustache's "inverted sections" (delimited by `{{^variable}}...{{/variable}}`).
+This section will be displayed if the variable is false or empty.
+
+Therefore, `{{^holeInWall}}1{{/holeInWall}}` will return "1" when the value of `holeInWall` is false, and will be empty otherwise.
