ui: refactor ui option related methods into UIOptions

[pve-manager.git] / www / manager6 / form / GlobalSearchField.js

/*
 *  This is a global search field it loads the /cluster/resources on focus and displays the
 *  result in a floating grid. Filtering and sorting is done in the customFilter function
 *
 *  Accepts key up/down and enter for input, and it opens to CTRL+SHIFT+F and CTRL+SPACE
