Check out the Elisp manual on pop-up menus, which use the function
x-popup-menu, which takes the same kind of menu structure as tmm-prompt.
C-h i Elisp RET Pop-up menus RET
An alternative to what you're trying to do would be to use the hydra
package:
https://github.com/abo-abo/hydra
Here is my toggle hydra, for example:
```
(defhydra jk-hydra-toggle (:color blue)
"Change"
("d" toggle-debug-on-error "Debug")
("w" writeroom-mode "Writeroom")
("i" ispell-change-dictionary "Change Ispell Dictionary")
("f" toggle-fill-unfill "Fill")
("F" follow-mode "Follow mode")
("t" orgtbl-mode "OrgTbl mode")
("y" typo-mode "Typo mode")
("q" nil "Cancel"))
(bind-key "s-r" #'jk-hydra-toggle/body)
```
Yeah, ok, so `ispell-change-dictionary` is not a toggle... But you get the
idea. ;-)
