## هبوط قطرة
|
|
|
|
يتم استخدام القوائم المنسدلة في CSS لإخفاء قائمة محددة مسبقًا داخل أحد الأزرار.
|
|
|
|
أمثلة:
|
|
|
|
`
|
|
<div class="dropdown">
|
|
<button class="dropbtn">Name</button>
|
|
<div class="dropdownContent">
|
|
<a href="#">One</a>
|
|
<a href="#">Two</a>
|
|
<a href="#">Three</a>
|
|
</div>
|
|
</div>
|
|
`
|
|
|
|
ثم يجب عليك تخصيص الطبقات في CSS
|
|
|
|
`.dropdown {
|
|
position: relative;
|
|
display: inline-block;
|
|
}
|
|
|
|
.dropbtn {
|
|
background-color: red;
|
|
padding: 10px;
|
|
}
|
|
|
|
.dropdown-content {
|
|
display: none;
|
|
position: absolute;
|
|
}
|
|
|
|
.dropdown:hover .dropdown-content {
|
|
display:block;
|
|
}
|
|
`
|
|
|
|
تحتاج إلى فئات div منفصلة لإنشاء الزر ، و div آخر لفصل قائمة ما يحتوي عليه الزر.
|

|
