A table in the database? Or an HTML table? What are the options in the dropdown? What should the contents in the table be? Etc. etc. You need to give a little more information than that.
i need to develop a html table… for example teacher selects class 7th in the dropdown so all the students under the category of class 7 forms a table….or as there are many online shopping website where we select a entry in a dropdown and then results are sorted out.
