The customization of the menus of the building and the indicators of the home page (also called one-pager), are done in your site API admin: "Groups of preference" (Image 1).

To create a group of tabs from the building menu, click "Add a preference group".

The group creation page is displayed (Image 2).

Name: Group label displayed in the Building menu
Order: Determines the order in which groups are displayed when multiple groups are created
This feature has been enhanced: folders in the buildings menu can now be displayed in the desired order in the menu (previously, groups were all grouped together at the top of the menu).
Please do not hesitate to contact your usual contact to implement this feature if required.
Icon: This option allows you to add an icon next to the group name. Icon HTML must be populated (https://fontawesome.com/icons)
Subject: Corresponds to the type of group created. Menu to customize the building tabs. (Building-one-pager for indicators).
Preferences menu: Assigns the Menu tabs you want to group to the group. To do this, first filter menu in the search bar, then simply click on the desired tab and then on the middle arrow, or double click on the tab name. Hold CTRL to select multiple tabs simultaneously

In image 3, we can see that the new group is well created and contains the Expenses, Works and Loans tabs of the building.
