ant-search (revision 2022-10-11)

/* This script hides all language options except the searched ones on the Dailymotion video details editing page. This is necessary because the language selector is no conventional HTML-based selector but an inferior JavaScript-based alternative by "ant.design", which lacks searching by typing. Since one can not select a language by typing its name on the keyboard, one would have to inconveniently scroll through the 183 items-long list to find the language.

This script can be used as a template for other sites that use the terrible ant.design selector.

Instructions: Paste this script into a user script manager  web browser extension such as "GreaseMonkey", "Custom Style Script", or "TamperMonkey", and add javascript:ant_select(); as a bookmarklet. If you wish to pre-select a language, put it inside the parenthesis, for example  javascript:ant_select("German"); .
