Dynamically adding a select box based on input from another select box
<p>I am building a form which will be used to enter the result of a student into a school database. Now the school has 2 sections for the 5th till 8th standard and 1 for the 9th till 10th. </p>

<p>Here is what i want to do, there should be a select box where the user can select the standard for which he wants to enter data, if the selected standard is within the limit of 5th to 8th then another select box needs to be dynamically added which will have the option to select "Section A" or "Section B". If the user selects 9th or 10th grade then no section select box should be there.</p>
