Sort dropdown list
问题 I am trying to sort a dropdownlist (selector) in html. I have two lists, a pre-selection which then should be used to define the content of the secont list. A short code sample: <!doctype html> <html class=""> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> </head> <body> <table width=100% border="0"> <tr> <td> </td> <td>Product</td> <td><select name="product" id="product" width="300" style="width: 300px"> <option></option> <option id="TLX"
