Resize the Bootstrap select element based on its contents

My HTML code includes a <select> element that is styled using Bootstrap 5.

<div class="col-md-12">
    <div class="mb-3">
        <label asp-for="Schedule.Minutes" class="control-label"></label>
        <select asp-for="Schedule.Minutes" class="form-control" asp-items="Model.MinutesOptions"></select>
        <span asp-validation-for="Schedule.Minutes" class="text-danger"></span>
    </div>
</div>

I have applied the class="form-control" to ensure consistent styling with my other elements. However, this causes the select element to stretch across the full width of its container by default.

In this scenario, I would like the select element to only be as wide as necessary to display its longest option in the list.

Is there an option in Bootstrap to achieve this layout?

Answer №1

One effective solution is to incorporate the w-auto class alongside the form-control class.

<select asp-for="ReportJobSchedule.Subject" class="form-control w-auto" asp-items="Model.MinutesOptions"></select>

Answer №2

While the Bootstrap utility class w-auto can be employed in conjunction with the form-control utility class to achieve this outcome, you also have the option to reach the same result by implementing additional custom styling to constrain the element's width to fit its contents.

Below is a demonstration of how you can accomplish this through customized CSS:

.custom-width-select {
    width: auto !important;
}

<select asp-for="Schedule.Minutes" class="form-control custom-width-select" asp-items="Model.MinutesOptions">  </select>
