Workaround für das alte bootstrap 2.0.1 in Joomla (siehe Link:
https://github.com/twitter/bootstrap/issues/4550)
----------------------------------------
A quick hack to prevent the dropdown menu from being cleared on touch
devices:
on line 143 of bootstrap-dropdown.js replace
.on('click.dropdown.data-api touchstart.dropdown.data-api', clearMenus)
with
.on('click.dropdown.data-api', clearMenus)
You won't be able to tap outside the menu to close it, but the dropdown
links will work.
