Steps to Reproduce

 http://10.1.3.45:8089/keikai-app/

1. open colour picker
2. partial cut off on a smaller screen like 1366x768 or mobile device (see pictures below)

The color picker is too big and cannot fully displayed (can't scroll down/up to use the full dialog)

Current Result

Vertical: on the right-border, can still customize (pick) colour

Horizontal: cut on the border and due to limited height, can not customize colour

Expected Result
