I have created a function called dynamicdropdown(), which will be called (onchange event) if you change the value of first dropdown list then in that the dynamic dropdown will be created and replace a div and will be shown as second dropdown list.So in this way you can create dynamic drop-down list in javscript.
Make all above as dynamic by using Mysql Database and PHP:
Below example I have a data base called “test” and has two tables called “language”, “framework”. So I will be going to fetch data from language and will make that as mys first dropdown. Ten I will fetching that data from framework and will make as second dropdown depending upon the changes value of first dropdwon.
