Event Timeline

This is a general UI problem related to displaying a lot of entries in an EnumProperty. You can try this text code. Not only that the prop is going to miss the entries on the left, but also the whole pop-up going to be cut on the left if the Blender window is resized (for instance half of the screen).

import bpy
from bpy.props import (


class whatever_props(bpy.types.PropertyGroup):
    def add_props(self, context):
        this_is_something = [(str(i), "Entry about something {}".format(i), 
                             "This is an entry number") for i in range(RANGE_MAX + 1)]
        return this_is_something
    some_something = EnumProperty(
        name="This is a test for EnumProperty size",

class LayoutDemoPanel(bpy.types.Panel):
    bl_label = "EnumProperty size screen fit Test"
    bl_idname = "SCENE_PT_layout"
    bl_space_type = 'PROPERTIES'
    bl_region_type = 'WINDOW'
    bl_context = "scene"

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

        scene = context.scene

        # Create a simple row
        col = layout.column()
        col.label(text="Test for the EnumProperty:")
        col.prop(scene.whatever, "some_something", text="")

def register():
    bpy.types.Scene.whatever = PointerProperty(type=whatever_props)

def unregister():
    del bpy.types.Scene.whatever

if __name__ == "__main__":

Edit: the workaround would be to use an operator with invoke_props_dialog and calling the look with the col.prop(scene.view_settings, "look", expand=True)
The similar would apply to the color spaces (get the right prop and expanding it if it uses some custom ui wrapper).

Still it is annoying as it only expands downwards, however it can be navigated with up and down arrow keys and double pressing enter.

The real solution would be to rethink the widget to handle better a lot of items.
