I'm using layout.popover(my_panel) to draw a panel in a box when it is clicked on, but I don't want that panel to be visible anywhere else in the UI. Just removing the bl_category setting from the panel class simply puts it in a category named "misc".

I realise that one solution could be to change the bl_region_type to something different, but if I change it to something like "TEMPORARY" it just gives me an error.

Is there a correct way to do this, or would it be better to do it from say the invoke method of an operator?


Add 'INSTANCED' to panel options

Edit Credit to @Nilson (finally twigged)

How to hide a panel that appears twice?

I found the solution .. and it was very simple. Just use: bl_options = {"INSTANCED"}. The popover menu is just an instance of the panel

enter image description here

If the 'INSTANCED' option is added to the panels bl_options the panel is not drawn directly in the UI, it is rather instanced via the popup call.

PLEASE Note. If the region is set to 'UI' a "Misc" category tab is added, which when selected shows no panels (No others in region and uncategorized) and (for me) segfaults blender when selected. The 'WINDOW' region appears a safe bet.

Test script using the Text Editor > Templates > Pythone > UI Panel Simple script modified to add to view3d UI (N) region. Making only the options edit confirms the panel no longer renders in the properties region.

import bpy

class HelloWorldPanel(bpy.types.Panel):
    """Creates a Panel in the Object properties window"""
    bl_label = "Hello World Panel"
    bl_idname = "OBJECT_PT_hello"
    bl_options = {'INSTANCED'}
    #bl_options = {'INSTANCED', 'DRAW_BOX'}
    bl_space_type = 'VIEW_3D' # 'PROPERTIES'
    bl_region_type = 'WINDOW'
    #bl_context = "object"

    def draw(self, context):
        layout = self.layout

        obj = context.object

        row = layout.row()
        row.label(text="Hello world!", icon='WORLD_DATA')

        row = layout.row()
        row.label(text="Active object is: " + obj.name)
        row = layout.row()
        row.prop(obj, "name")

        row = layout.row()

def draw(self, context):
def register():

def unregister():

if __name__ == "__main__":

Tip. If set an enum to a garbage value can look at the error message to get allowable values

TypeError: validating class: enum "FOO" not found in 

Fwiw 'HUD' adds panel to operator redo panel.
