Filter Builder
The panel where someone builds the conditions for a table: typed fields, the operators that fit each type, the right editor for each value, and one level of grouping for this and (that or the other). The footer says the whole filter in plain words next to how many rows it leaves. The same file exports applyFilter, describeFilter and countConditions, and the filter itself is plain JSON you can save or send to a server.

The decision inside it
An unfinished row is not an error
A new row has no value yet, and treating that as a failed condition would empty the table the moment someone clicks Add filter. So an unfinished row gets a dashed edge, stays out of the sentence and the count, and applyFilter ignores it. The table only changes when a condition means something.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Filter Builder for this.
Install it: npx shadcn@latest add @layro/filter-builder
Import it from @/components/ui/filter-builder.

Props
Read from the component’s own TypeScript interface when the site is built, so this table cannot drift from the file you install.
| Prop | Type | Notes |
|---|---|---|
fieldsrequired | FilterField[] | What can be filtered, in the order it is offered. |
value | FilterGroup | The filter, when you hold it. |
defaultValue | FilterGroup | The filter to start with, when you do not. |
onChange | (filter: FilterGroup) => void | Called with the filter on every edit, or once per Apply when `onApply` is set. |
onApply | (filter: FilterGroup) => void | Promise<void> | Adds Apply and Cancel and keeps edits as a draft until Apply. Return a promise to show it working; reject to show the error. |
resultCount | React.ReactNode | ((filter: FilterGroup) => React.ReactNode) | What the filter leaves: "12 of 48 deals". A function is given the filter being edited, drafts included. Numbers in a string tick when they change. |
maxDepth | number | How deep groups may nest. 1 turns groups off. Default 2. |
noun | string | What is being filtered, in the plural, for the empty state: "deals". Default "rows". |
