Table of Contents

The Table of Contents, briefly TOC from now on, is a space where all the layers and the layers groups are listed. Through this panel it is also possible to carry out the following operations:

• Add and remove layers and groups

• Perform a search between layers

• Change the position (and consequently the display order in map) of layers and groups

• Set some display options directly from the panel

• Manage layers and groups and query layers through the toolbar actions

TOC Settings and Toolbar

The user can access the TOC with the button on the top-left corner of the map viewer. Once this is done, the following panel will appear:

With the TOC Toolbar the user can:

Here the user can:

• Enable/disable the opening of the TOC on map initialization, through the button.

• Change the TOC theme by choosing between Default Theme or Legend Theme, through the button. With the Legend Theme the user does not have the ability to drag and drop the position of groups/layers. This mode provides a simplified and lighter TOC when necessary.

Search for layers

With the TOC it is also possible to perform a search between the added layers. This operation can be done simply by typing the name (o part of it) of the layer in the search bar:

Choose layers and groups position

The user can decide to change the position of a Layer within the TOC by clicking on the layer's drag and drop icon .
It is possible to change the position of a layer within its group or move it into a different groups. Once this is done, also the order of the layer in the map changes accordingly.
Below is an example of changing the layer position through the drag and drop function.

The same operation can also be done with any Group of layers.

Layers position can also be changed by clicking on the Layer settings button available in the toolbar. It appears once a layer is selected in TOC. This button opens a panel where the user can choose the destination group:

Display options in panel

Directly from the TOC UI, the user can access different kind of display options. In particular, for layers, it is possible to:

• Enable/disable the layer visibility by using the check box to the left side of the layer leaf

• Expand or collapse the layer legend.

• Tune the layer transparency in map by scrolling the opacity slider.

For groups the user can instead:

• Expand or collapse layers or groups inside.

• Enable/disable the group visibility by using the check box to the left of the group leaf

When the user turns off the visibility of a group, the visibility in map of all layers and groups inside it changes accordingly but their original visibility state in TOC remain untouched; simply all nested elements are grayed out to indicate they are not visible on map and other functions (e.g. via context menu) remain available.

Group Settings and Toolbar

Once a group is selected the following toolbar appears and the user can:

• Add layer to selected group through the button (it is possible to add one or more layers to the group)
