DB 11.2 - APEX 5.1 - I have setup a Dynamic List used as a navigation menu (left side).
Those entries, which are assigned to a parent_id_page are shown below that parent entry - fine - as expected.
But the (sub-) entries are shown as entry on the same level as the parent entries as well.

Question: How can one avoid a.m. behaviour ?
Here are my entries:

Thanks in advance

My SQL Query reads:

,null image_attribute
,null image_alt_attribute
,null as attr1

where ':'||GM_GUI_MENU.GM_MENU_MODULE||':' like
