I currently have an excel sheet with dependent drop down lists but I constantly keep having to add more countries along with their appropriate department and cities. I was wondering if it was possible to create a web based dropdown in excel?

I found this website Get Country State City Hierarchy - Get list of country, state, city using GeoNames

They show an example that populates their dropdowns from geonames, unfortunately its web based. I would love if I could do in excel as that website. I would appreciate any help, thanks.

This is the html from that link.

<h1>Get a list of country/state/city in a hierarchy using geonames webservice </h1>

<p>Here you can get a hierarchy of places. Get place information like a tree structure. For example you can take north america, and in that you can pick united states. and from the list of states which will be 50 you can pick one state for which you will get a list of counties. and by selecting a county you will get a list of all the cities. Liks this you can do for any part of the world. But i couldn't get information as expected for australia. May be i did not understand the administrative levels of austraila. In the unites states it is state/county/city and in parts of europe it is province/region/city. The following works very well for United States and Europe. I have to test for other parts of the world. Below is the code explanation and references.</p>
</div>


<div class="contents">

<p><span>Continent:</span> <select name="continent" id="continent" onchange="getplaces(this.value,'country');">
<option value=""></option>						
</select>
</p>

<p><span>Country:</span> <select name="country" id="country" onchange="getplaces(this.value,'province');">
<option value=""></option>						
</select>
</p>

<p><span>State / Provice:</span> <select name="province" id="province" onchange="getplaces(this.value,'region')">
<option value=""></option>
</select>
</p>

<p><span>County / Region:</span> <select name="region" id="region" onchange="getplaces(this.value,'city')">
<option value=""></option>
</select>
</p>

<p><span>City:</span> <select name="city" id="city">
<option value=""></option></select>
</p>
</div>

  <p>Code sample will appear in a few days... Till that you can just copy this pages source code and you can use it. it is simple and straigh forward.</p>

Excel Facts

Repeat Last Command
Pressing F4 adds dollar signs when editing a formula. When not editing, F4 repeats last command.
Solved: Web Based Dropdown list

It took me all week but I finally figured it out. If anyone is looking for the solution, this is what I did. I created a tab with data validation lists and different tabs for each selection (region,country...). I created a web query connection to for each reference. Once I successfully created the query connections, I changed the parameters dependent from the previous selections. Ben Sullins website helped me immensely.
