Overview
Bootstrap Maxlength is a visual feedback indicator for the maxlength attribute. For more info please visit the plugin's
Home or
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.
