A collection of TagHelpers for ASP.NET Core that make utilizing the Bootstrap 5.x library easier to use for developers. Designed to reduce code effort substantially
These tag helpers are only for markup display, your web project must properly include references to Bootstrap and must abide by all license and other requirements of Bootstrap for the functionality to be utilized here. For more on how to include Bootstrap within your project please reference their documentation.
You must modify your _viewimports.cshtml file by adding
@addTagHelper *, ICG.AspNetCore.Utilities.Bootstrap5TagHelpersThe goal of these tag helpers is to reduce the redundant coding, and compliance with various features of not only the Bootstrap library but form patterns. Within the "Sample" project you will find examples of all tag helper usage. However, the below shows a quick example of the power of these tag helpers.
The following markup is how you would output a model-bound field for a password field, including a note on complexity and validation.
<div class="mb-3">
<label asp-for="Password" class="form-label"></label>
<input asp-for="Password" class="form-control" />
<span asp-validation-for="Password" class="text-danger"></span>
<div class="form-text text-muted">Must be 8 characters with letters & numbers</div>
</div>This is a total of 306 characters with spaces or 268 without. Granted we get some help with auto-complete etc.
You can take the entire above example and simplify it to the following
<form-text-input asp-for="Password">
<form-note>Must be 8 characters with letters & numbers</form-note>
</form-text-input>This is a total of 126 characters with spaces or 112 without. With intellisense, the actual typing characters are much less. Your form view is also substantially reduced, making lines of code per form reduced. For forms without notes the markup improvement is even better.

If you find that we are missing a particular tag helper, we welcome contributions!
The tag helpers automatically inspect form elements and add a "required" css class in addition to the form-label class default allowing for indication of required fields easily with CSS such as the following.
label.required:after {
content: " *";
color: red;
}
