Overview
Bootstrap Maxlength is a visual feedback indicator for the maxlength attribute. For more info please visit the plugin's
Homeor
Github Repo.
Usage
Bootstrap Maxlength's Javascript files are bundled in the global plugin bundles and globally included in all pages. However, the maxlength functionality requires a manual Javascript initialization.
