Variable: transient-show-during-minibuffer-read

transient-show-during-minibuffer-read is a customizable variable defined in transient.el.

Value

nil

Documentation

Whether to show the transient menu while reading in the minibuffer.

This is only relevant to commands that do not close the menu, such as commands that set infix arguments. If a command exits the menu, and uses the minibuffer, then the menu is always closed before the minibuffer is entered, irrespective of the value of this option.

When nil (the default), hide the menu while the minibuffer is in use. When t, keep showing the menu, but allow for the menu window to be resized, to ensure that completion candidates can be displayed.

When fixed, keep showing the menu and prevent it from being resized, which may make it impossible to display the completion candidates. If that ever happens for you, consider using t or an integer, as described below.

If the value is fixed and the menu window uses the full height of its frame, then the former is ignored and resizing is allowed anyway. This is necessary because individual menus may use unusual display actions different from what transient-display-buffer-action specifies (likely to display that menu in a side-window).

When using a third-party mode, which automatically resizes windows
(e.g., by calling balance-windows on post-command-hook), then
fixed (or nil) is likely a better choice than t.

The value can also be an integer, in which case the behavior depends on whether at least that many lines are left to display windows other than the menu window. If that is the case, display the menu and preserve the size of that window. Otherwise, allow resizing the menu window if the number is positive, or hide the menu if it is negative.

This variable was added, or its default value changed, in transient version 0.8.0.
