<label>What is the school type? Select one</label>
<select1> inputs present the user with a drop-down list of options of which they can only choose one. In this way you can pre-define choices and this helps you ensure that data collected adheres to what you have specified.
Every <select1> MUST contain one <label> tag which specifies the question presented to a user.
You can then specify as many <item> tags as you require. However, each item MUST contain one <label> and one <value> tag. The <label> specifies the text the user sees as a choice and the <value> specifies what is stored in the database when a user selects this choice.
Within the <select1> tag you can also specify the attribute required="true" if neccessary.
