textual-tags

This library provides a custom tags widget called Tags, which can be easily added into your existing textual application.

Requires a Nerdfont to render the round corners of the Tag labels.

Features

• Can be initiated with a predefined set/list of tags, similar entries will be ignored
• Consists of a TagInput, with autocompletion powered by textual-autocomplete for existing tags and displayed tags wrapped in a flexbox-like container
• Two different ways to display the tags (with x at the end or without)
• Option to also add new not predefined tags, which are then also available for autocompletion
• vim-like completion control
