Your question is kind of vague; however, I think I get what you're asking. It looks like your data for the select field is static, so you may try it like this:
Then use the following instead of the HTML you have there:
<%= select_tag(:country, options_for_select([['Select Country', '0'], ['Albania', 'Albania']], '0'))%>
This will generate the following:
<select name="country" id="country">
<option value="0" selected="selected">Select Country</option>
<option value="Albania">Albania</option>
</select>
If you wanted to have a different default selected, just specify it at the end. For example:
<%= select_tag(:country, options_for_select([['Select Country', '0'], ['Albania', 'Albania']], 'Albania'))%>
Generates:
<select name="country" id="country">
<option value="0">Select Country</option>
<option selected = "selected" value="Albania">Albania</option>
</select>
Hope that helps.
