Firstly your question is not cler if you are using static combobox as you used in Html code then it will be the code..

<combobox id="box" width="100px" mold="rounded" >
        <comboitem id="a" label="value a" />
        <comboitem id="b" label="value b" />
        <comboitem id="c" label="value c" />
    </combobox>

If you are saving the HTML code for select box in DB then you can use the below code to parse the HTML code and save its value and name either in Model or in hashtable,later you can use to populate the combobox model.
