Related tables: insert a child only from a parent's form

Hello, From a parent/children 1:M relationship, we need to allow users to add, modify or delete children (non-geographic table) from a parent's form (geographic table, unmodifiable). A new child must also inherit characteristics from the parent. When we go through the parent's form to create a new child object, it works. On the other hand, we can also create a new child directly with the Edit menu and the Data menu: this is a problem, because in these cases, the new record doesn't retrieve any attribute from the parent and the user shouldn't have to choose them. Is there a way to handle this case. We should be able to force the user to go through a parent's form to create a child.

There is indeed an option Hide layer in the list (last checkbox) to prevent to display the table in the attribute table panel, to force to open the parent table and click on the parent table line to display the filtered child table. See https://docs.lizmap.com/current/en/publish/lizmap_plugin/attribute_table.html#at-the-layer-level

We could detect this option, and say if it is checked, we must prevent the user from opening the form for the child layer too.

We should probably change the label of this option, and also the tooltip

Thank you! We have just tested: it works well. But this button does only the half the job: if we could hide the table in the same way in the Edit menu, that would be perfect.

Exactly, we must extend the behaviour to the Edit menu !
