Good evening MrRobinW and MrStephenEdgar!
Japan is currently rainy season.
I like rainy days as well as sunny days.

Well, I need your help again…(Of course my website is going well these days!)

This time, I wanna remove a <option> tag
with adding php function into “function.php” of WordPress.

At a create-topic page, users can select one specific forum.
And the souse code is like…

<label for="bbp_forum_id">in forum</label><br />
<select name="bbp_forum_id" id="bbp_forum_id" tabindex="103">
<option value="" class="level-0">select：</option>
<option class="level-0" value="1">Apple</option>
<option class="level-0" value="2">Banana</option>
<option class="level-0" value="3">Grapes</option>
<option class="level-0" value="4">Elephant</option>
</select>

In my website, these 4 forums has been set to the public,
and I don’t wanna change the setting.

However, I do not show the last one (Elephant!) to every users at the time.
In this case, what code should I put into the “function.php” of WordPress.

For me, The case is too difficult to solve.orz
Would you please advice me…

many thanks
