Expanse Theme Mega Menu Nesting Not Working

Topic summary

Issue: Attempt to organize a Shopify navigation (Expanse theme mega menu) by alphabetized groups fails when creating a second-level nest. The user wants to place a subcategory (“ACROPASS”) under a parent group (“A–E”).

Behavior: When dragging the subcategory beneath the parent, the UI underline turns gray and the item won’t indent (i.e., won’t become a child/second-level item). A screenshot is provided to illustrate the drag-and-drop state.

Context: Goal is to group collection categories alphabetically with nested menu items (nesting = making a child menu item under a parent).

Status: No solutions or workarounds provided yet; the request is for guidance on enabling second-level nesting in the Expanse mega menu. The attached image is central to understanding the issue. The thread remains unresolved.

Hello, I’m trying to make my menu nicer by grouping the categories by alphabet.

However, I cannot make a second nest as below, when I drag the ‘ACROPASS’ (subcategory) under ‘A-E’, the underline turns gray and I cannot make it nested. Could anyone help with this please?
