Contract Hide Option Choice For Free

You could save the <option> elements you want to hide in hidden select element: $('#visible'). on('change', function () { $(this).

Here's a really simple way to achieve this. Simply have a show and hide function. The hide function will just append every option element to a predetermined (hidden) span tag (which should work for all browsers) and then the show function will just move that option element back into your select tag. ;)

A disabled option is unusable and un-clickable. The disabled attribute can be set to keep a user from selecting the option until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript is required to remove the disabled value, and make the option selectable.

HTML for Select Hidden ElementHide a select box by putting styling options on it using HTML and CSS to make it invisible. The two principal ways to do this using CSS and HTML to hide an element are with the visibility style attribute and the display style attribute.

Every Bootstrap dropdown button or link has an ::after selector in CSS. ::after selector is often used to insert some text after the content of the element. In this case, the content is a dropdown arrow. To remove it, just make the content go 'none'.

Setting this property to none will do the job. It explicitly tells the browser to not assign any other value to that property, which in turn results in the removal of the default arrow icon.
