BS4 kiritish guruhlari
Bootstrap 4 kiritish guruhlari (input group)
.input-group klassi — kiritish maydoni oldiga yoki orqasiga "yordamchi matn" sifatida belgi (icon), matn yoki tugma qo‘shib, uni boyitish uchun ishlatiladigan konteyner.
Yordamchi matnni kiritish maydonining oldiga qo‘shish uchun .input-group-prepend dan, orqasiga qo‘shish uchun esa .input-group-append dan foydalaning.
Va nihoyat, ushbu yordamchi matnni bezash uchun .input-group-text klassini qo‘shing.
Misol
<form>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text">@</span>
</div>
<input type="text" class="form-control" placeholder="Username">
</div>
<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Your Email">
<div class="input-group-append">
<span class="input-group-text">@example.com</span>
</div>
</div>
</form>

Maslahat: Kiritish guruhi to‘g‘ri pastki tashqi chekinishga (margin) ega bo‘lishi uchun .mb-3 yordamchi klassidan foydalanamiz. Yordamchi klasslar haqida BS4 yordamchi klasslar bobida batafsil o‘qing.
Kiritish guruhi o‘lchami
Kichik kiritish guruhlari uchun .input-group-sm klassidan, katta kiritish guruhlari uchun esa .input-group-lg dan foydalaning:
Misol
<form>
<div class="input-group mb-3 input-group-sm">
<div class="input-group-prepend">
<span class="input-group-text">Small</span>
</div>
<input type="text" class="form-control">
</div>
</form>
<form>
<div class="input-group mb-3">
<div class="input-group-prepend">
<span class="input-group-text">Default</span>
</div>
<input type="text" class="form-control">
</div>
</form>
<form>
<div class="input-group mb-3 input-group-lg">
<div class="input-group-prepend">
<span class="input-group-text">Large</span>
</div>
<input type="text" class="form-control">
