The content in the select drop-down box in HTML was too long, causing part of it to be covered. I tried various methods but had no clue. Finally, I added the title attribute to the option and found that the problem was solved. Today, I encountered such a problem: the content in the drop-down box in the query column was too long, causing part of it to be covered.
I checked some information, some said to use function control, some said to use event control, some couldn't understand, and some were too complicated to implement. Later, I asked my colleague if there was any simple method. He told me to add the title attribute to the option, so I tried his method and finally found that this method worked. In this way, I want to record it to prevent myself from forgetting.
1. The specific examples are as follows

The code is as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<style type="text/css"> 
#area option{ 
width:140px; 
} 
</style> 
</head> 
<body style="width:80%; height:100px; text-align:center;"> 
<p id="p_select"> 
<label for="area">字母：</label> 
<select id="area" name="area" style="width:150px;"> 
<option value="0">全部</option> 
<option value="1" title="AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA">AAAAAAAAAAAAAAAAAAAAAAAAAAAAAA</option> 
<option value="2" title="BBBBBBBBBBBBBBBBBBBBBBBBBBBBBB">BBBBBBBBBBBBBBBBBBBBBBBBBBBBBB</option> 
<option value="3" title="CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC">CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC</option> 
<option value="4" title="DDDDDDDDDDDDDDDDDDDDDDDDDDDDDD">DDDDDDDDDDDDDDDDDDDDDDDDDDDDDD</option> 
<option value="5" title="EEEEEEEEEEEEEEEEEEEEEEEEEEEEEE">EEEEEEEEEEEEEEEEEEEEEEEEEEEEEE</option> 
<option value="6" title="FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF">FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF</option> 
<option value="7" title="GGGGGGGGGGGGGGGGGGGGGGGGGGGGGG">GGGGGGGGGGGGGGGGGGGGGGGGGGGGGG</option> 
<option value="8" title="HHHHHHHHHHHHHHHHHHHHHHHHHHHHHH">HHHHHHHHHHHHHHHHHHHHHHHHHHHHHH</option> 
<option value="9" title="IIIIIIIIIIIIIIIIIIIIIIIIIIIIII">IIIIIIIIIIIIIIIIIIIIIIIIIIIIII</option> 
</select> 
</p> 
</body> 
</html>
