Dropdown appears on selection from first dropdown

[9h1lo]

need some suggestions here

have a php script doing a search using post with various options in a dropdown and a query in a textbox

now I would like that when a specific option is selected (only 1) in the dropdown, the textbox changes into another dropdown with pre-defined options

how would this be possible ?

Have a function that runs on the onChange event of the dropdown, and checks the value that has been selected. If it matches the defined value, make the dropdown visible, and the text box invisible.

function show_dropdown(){
if(document.getElementById('dropdownid').value=='the specified value'){
document.getElementById('textboxid').style.display=none;
document.getElementById('newdropdownid').style.display="block";
}
else{
document.getElementById('textboxid').style.display=block;
document.getElementById('newdropdownid').style.display="none";
}
}

And your HTML

<input type=text id="textboxid">
<select id="newdropdownid" style="display:none">
...
</select>

}

thanks for the tip...is this javascript or php ?

Javascript, since PHP can't actually do it.
