Too Long; Didn't Read
The multiselect form is a form that can display multiple items of a single selection. Not all <select> tag elements can be styled out of the box as designers would like to. In this small tutorial, I share my experience in solving this problem based on my knowledge of CSS and vanilla JS. I used CSS for SVG icons, but this wasn’t quite effective and it’s better to keep them as header files. The main thing about the <select tag is that in smartphones, the engines show the multiselection when you focus on the tag.
