</html>When the <select> is required, then it's working fine.
But The problem is that when I removed "required", it's Label Floating without the selected option.
How can I maintain the floating label in this case?
I'm missing anything? Or do we need JavaScript?
So the idea is not to float the label when it is empty.
I resolved the input issue using link
CodePudding user response：
Simply remove :valid selector, valid is always true if the input in not required.
so after removing this:
.select-text:valid ~ .select-label
You'll face another problem which is keeping the label up after :focus is removed if the user selects an option.
so you'll need to add onchange event
onchange="this.dataset.chosen=this.value;"
Then you can easily make the label stay if the user has selected an option.
.select-text[data-chosen] ~.select-label
This way the label stays up if the select has a value.
it becomes like the following snippet:
.body {
position: relative;
font-family: 'Roboto', 'Helvetica', 'Arial', sans-serif;
}
.wrap {
position: absolute;

This new solution works if the user selects empty option, the label come down,
I simply added the empty value selector to keep the label up,
and added a blur() event when the select change to smooth everything.
Check out the snippet:

Its working as expected.
When the <select> is required, then it's working fine.
This is happening because of this style .select-text:valid ~ .select-label
When the select is required, if you select the first option whose value is null, then your select is invaid and the css style .select-text:valid ~ .select-label wont work whch means your label will be in grey colour. If the select is not required, then if you select first option, then the .select-text will be in valid state, and the style .select-text:valid ~ .select-label will be applied, which makes the label small and blue.
To fix this, we have to use a css javascript solution.
I have implemented the solution by refering this answer.
