How TO - Responsive Sidebar
The hidden element has similar traits as display: none in Safari, IE, Project Spartan needs checking where the option is visible in dropdown but is not selectable. Once a value has been set the :invalid pseudo-class will be dropped. You can optionally also use :valid if you so wish.
Most browsers support this pseudo-class. This works best with custom styled select elements; In some cases i. You can find some examples and more about compatibility at developer. I had the same problem and while searching came across this question, and after I found good solution for me I would like to share it with you guys in case some one can benefit from it. I hope this helps someone :. Here I have modified David answer accepted answer.
On his answer, he put disabled and selected attribute on option tag but when we also put hidden tag then it will look much better. By adding an extra hidden attribute on option tag, will prevent the "Select your option" option from being re-selecting after the "Durr" option is selected.
User should not see the placeholder in select options. Here is a CSS solution that works beautifully. The content is added and absolutely positioned relative to the container after the containing element via :after pseudo-class. It gets its text from the placeholder attribute that I defined where I used the directive attr placeholder.
Another key factor is pointer-events: none - this allows clicks on the placeholder text to pass through to the select. I add the. All you have to do is create a simple list with few data attributes. The code automatically turns the list into a selectable dropdown. It also adds a hidden input to hold the selected value, so it can be used in a form.

In React, for a controlled component , you cannot add the selected attribute to your options. React handles the state of the select via a value attribute upon the select itself, along with a change handler, where the value should match one of the value attributes within the options themselves. Since it would be improper and in fact would throw an error to add the selected attribute to one of the options, what then?
The answer is simple once you think about it. Since we want our first option to be selected as well as disabled and hidden , we need to do three things:. In Angular we can add an option as placeholder that can be hidden in option dropdown. We can even add a custom dropdown icon as background that replaces browser dropdown icon.
