Comments component
<wy-comments> | WyComments
Weavy comments component to render a list of comments next to something like a product, page, blog post etc.
The comment list can show rich comments with markdown formatting including code syntax highlight. Comments can have uploaded images, attached files and cloud files with full browser preview of 100+ formats. Polls, video meetings, rich link embeds, tags and mentions can be used, and users can react with predefined emojis to each comment.
The editor features markdown preview, including code syntax highlighting. It has buttons for adding polls, video meetings, images, files and cloud files. Mentions brings up a user selector. Drafts are automatically saved for each comment list.
Each comments component requires an app identifier (uid), which automatically creates a corresponding app on your Weavy environment when the component is first initialized. It's also recommended to specify a readable name of the comment list, to get better readable notifications from the app. It's often useful to base the uid on something that identifies the location where the component is rendered. Typically you would use something like a product id, page id or path.
Component layout
The component is block-level with pre-defined CSS styling to adapt to flex- and grid-layouts as well as traditional flow-layouts. It's usually recommended to use a proper flex-layout for the container you are placing the component in for a smooth layout integration, but for comments it can also be common to place the component in a height growing flow-layout beneath a subject element.
The height grows with the content per default. Content is automatically loaded during scrolling when the last content becomes visible (aka infinite scrolling). If placed in a flex- or grid-layout or if an explicit height is set, the component becomes scrollable.
The content within the component is per default aligned to the edges of it's own box. It's recommended to add your default padding to the container or to the component to make it fit your design. If you want the component to go all the way to the edges of your container without any outermost roundness or padding, you can set the padding to 0 and set the --wy-border-radius-outer to 0 to make the component align nicely with the edge.
You can add additional styling using CSS Custom Properties and CSS Shadow Parts and further customization using slots.
