Gallery Alignment Issue: Dashboard Gallery Does Not Align with Selected Subcategory

Hi everyone,

I am building a hierarchical navigation menu in Power Apps using galleries.

When a user clicks a subcategory, the corresponding dashboards are displayed in a gallery on the right side.

My issue is that the dashboard list always appears at a fixed position on the right and does not align with the selected subcategory.

For example:

When I click Subcategory 1, the dashboard list appears correctly.

When I click Subcategory 2, the dashboard list still appears at the same position (at the top) instead of moving down and aligning with Subcategory 2.

I would like the dashboard list to be displayed beside the selected subcategory so users can easily identify which dashboards belong to which subcategory.

Desired Result

Category 1
 ├─ Subcategory 1  → Dashboard List appears beside Subcategory 1
 ├─ Subcategory 2  → Dashboard List appears beside Subcategory 2

Category 2
 ├─ Subcategory 3  → Dashboard List appears beside Subcategory 3
 ├─ Subcategory 4  → Dashboard List appears beside Subcategory 4

I have attached a screenshot illustrating the issue.

Has anyone implemented a similar expandable menu structure before?

Is there a way to dynamically position the dashboard gallery based on the selected subcategory?

Should I use a nested gallery, flexible height gallery, component, or another approach?

Any sample formulas or design recommendations would be greatly appreciated.

Thank you!

Use a three-level nested gallery structure in Power Apps. The first gallery displays Categories, a nested gallery displays Subcategories under each category, and a second nested gallery positioned beside each subcategory displays the associated Dashboard list. This creates a hierarchical layout where each dashboard is grouped under its corresponding subcategory and category.

visually as two columns:

Left	Right
Category 1
↳ Subcategory 1	Dashboard A
	Dashboard B
	Dashboard C
↳ Subcategory 2	Dashboard D
	Dashboard E
Category 2
↳ Subcategory 3	Dashboard F
↳ Subcategory 4	Dashboard G

Hi @WC-08072359-0,

This is a duplication of this thread, which already has a number of responses. Please do not create new posts as everyone has to start again. I have added some additional information on the thread and also updated my blog to make things a bit clearer.

Having three-level nested galleries is impossible in Power Apps. This is their limitations.

Hi @WC-08072359-0,

Nested - yes impossible, put cascading as per my blog is certainly able to be done.
