For me, this is the frustrating part of hanging around online support forms.
I can think of a way but can't explain it well enough for other to follow along.

Richard has a series of videos ( 6 parts ) called "Big Button Forms" starting at https://599cd.com/blog/display-article.asp?ID=3296

With a bit of a redesign on your system this can be adapted to suit your needs.
Your Main Menu would start with three buttons, one for each category of form.
Then separate tables for each Form Type.
Then the buttons would update to suit your selections.

Cascading Comboboxes as a Main Menu is also a possibility, or cascading Listboxes.
Working in much the same manner as the Big Buttons.

I have a YouTube link too another video from Richard that might help?

As you add new buttons to the Main Menu then you can use this technique to quickly rearrange the sort order in the underlying tables.

Thank you, Debbie.  I will have to consider this for when I have time to redesign my Main Menu.  In the meantime, I wleocme any other suggestions or ideas.

Sorting would be quite unwieldy in this situation because all the X Y positions of every button on the form would have to be changed whenever any change is made.

If it doesn't have to be buttons, consider using hyperlink text as menu items.  The picture below is actually a subform with all borders turned off, text retrieved from a table (that can be easily sorted), and text formatted as clickable hyperlinks, which will run the OnClick event to perform the desired action.

A textbox has a property that allows the text to be always shown as a hyperlink.  When the user hovers over the link, the mouse pointer will turn into a finger icon.
