What is the bug?

Collapse a group in the legend.

lizMap.events.on({
    uicreated: function(e) {
        $('#group-test td a.expander').click();
    }
});

When a add this js script to "\media\js\testmap\" or in the default "\media\js\default" map both does not work anymore.

Themes/JavaScript enable on the repositories.

Steps to reproduce the issue

Add js script from example in lizmap v3.7.2 doc.

I guess you mean this link ? https://docs.lizmap.com/current/fr/publish/customization/javascript.html

Indeed, it needs an update.

@Gustry I'm not even sure we should keep this example. Should we communicate on the Activate first map theme on startup instead?

[rldhont]

Here is the new way

lizMap.events.on({
    uicreated: function(e) {
        for (const treeItem of lizMap.mainLizmap.state.layerTree.findTreeLayersAndGroups()) {
            if (treeItem.type != 'group') {
                continue;
            }
            if (treeItem.name != 'test') {
                continue;
            }
            treeItem.expanded = true;
        }
    }
});

Can i collapse several groups using commas ??

[Gustry]

@NvBgm Does using a QGIS theme not enough for your needs ?

[josemvm]
