Question

I have a range of items in an HTML drop-down menu that I need to find with jQuery so I can then hide them [using .css('display', 'none')].

They are (in this example) all the ones between <option>---- Articles</option> and <option>---- Jargon Buster</option> except for the first six items in this range!

Other than these first six, the number and text of all the other options within this range will vary (apart from from the leading ------ ).

I’m thinking maybe I can utilse the selectors $("#edit-menu-parent option:contains('---- Articles')" and $("#edit-menu-parent option:contains('---- Jargon Buster')" somehow, but I’m not sure how these can be used to get the items in between them.

Any ideas?

<select id="edit-menu-parent" class="form-select menu-title-select" name="menu[parent]">
<option>---- Clients</option>
<option>---- Testimonials</option>
<option>-- Resources</option>
<option>---- Articles</option>
<option>------ Accessibilty Articles</option>
<option>------ Usability Articles</option>
<option>------ Charities Articles</option>
<option>------ Public Sector Articles</option>
<option>------ Web Development Articles</option>
<option>------ Social Media Articles</option>
<option>------ Are Your Online Forms</option>
<option>------ Benefits of Web Standards</option>

Answer 1

In my test HTML file I tried both calling .hide() and .css("display", "none"), but none of them seemed to work in Safari(Mac), but worked as expected in Firefox(Mac).
First I thought that the jQuery selector is wrong, but the same happens even if I select simply #edit-menu-parent option.

I created a script that finds the index of start and end elements and then slice()-s out the required items for deletion. However, I used remove() which didn’t work otherwise. Since it was said that the first six elements must remain there, I have this start+6 there.

var options =  $("#edit-menu-parent option");
var start = options.index( $("option:contains(---- Articles)" ));
var end = options.index( $("option:contains(---- Jargon Buster)" ));
options.slice(start+6,end).remove();
