你们能告诉我如何设计下拉列表的项目吗?我想在列表项之间留出更多间距,也许每个项下都有一个边框?
<select class="text_select" id="field_14" name="field_14" style="opacity: 0;">
<option value="- Select -">- Select -</option>
<option value="0 - $2m">0 - $2m</option>
<option value="$2.1 – $5m">$2.1 – $5m</option>
<option value="$5.1 - $10m">$5.1 - $10m</option>
<option value="$10 -$20m">$10 -$20m</option>
<option value="Greater than $20M">Greater than $20M</option>
</select>
