Sorting or Filtering drop down content?
How to change the code below to improve the sorting procedure? I need to sort accurately those items listed in the dropdown content but when I type letter b the word "About" will go first instead of "Base" and "Blog". I attached the code below to let you (Experts) see the problem easily. I want here to sort perfectly as alphabetical order. Any help please!

Hi, Swatantra, the code won't work when i add word "Absolute". I have two words who start letter, A like "About" and Absolute. When I type A, the two words will come out but when i type Ab, the two words will longer come out!
<div id="myDropdown" class="dropdown-content">
<input type="text" placeholder="Search.." id="myInput" onkeyup="filterFunction()">
<a href="#about">About</a>
<a href="#base">Base</a>
<a href="#blog">Blog</a>
<a href="#contact">Contact</a>
<a href="#custom">Custom</a>
<a href="#support">Support</a>
<a href="#tools">Absolute</a>
</div>
