How to include <HTML> inside <%%> in JSP?
Question
I am new to jsp and am stuck at building a dropdown using a list variable. For static content, I used to following code:
<form method="post" action="Index.jsp">
<select name="item">
<option selected="selected"> -- Please choose --</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<input type="submit" value="Submit">
</form>
This worked well. Now to populate the list using a List variable 'list' I searched for any solution but in vain. After much search I couldn't find how to populate the dropdown list, after which I tried the following which did not work as well:
<form method="post" action="Index.jsp">
<select name="item" path="list">
<%for(String element : list){
PrintWriter writer = response.getWriter();
writer.println("<option value="xyz">"+element+"</option>");
}
%>
</select>
<input type="submit" value="Submit">
</form>
Is there a way I can accomplish this? Thanks in advance.

Use jsp expression tag <%="string"%>
<%for(String element : list){%>
<option value="<%=element%>"><%=element%></option>
<%}%>

Try this
<select name="item" path="list">
<%for(String element : list){
%>
<option value="<%=element %>"><%=element %></option>
<%
}
%>
</select>
Here you can see the value of 'element' in SELECT and get the same in the click
<%=bla%> this is the Expression tag in JSP
