Is there a way to access another element (& onclick) with jQuery passthrough? For example, to achieve the below:
<div id="that"></div>
<a ui-jq="slideUp">slide Up #that</a>
From the docs it isn't clear :)
ui-jq is not the answer to everything, especially for what you're trying to do.
Instead, try using ui-show and related directives alongside some custom CSS. Or if you're using bootstrap, check out the code for the collapse directive.
Overall, you're better off using Angular to simply toggle a class and handling the sliding and transitions that way. Or you can try creating a custom directive if CSS transitions won't cut it.
