About this block

Advanced Filter Builder is the query composer card, three condition rows each with a closed field Select, an operator Select, and a value Input (event name is checkout_completed, country is one of US, CA, DE, plan is not Free), an AND / OR match toggle in the header, an Add condition button, and a footer stating 212 events match in the last 30 days beside Save as view and Apply filters.

Conditions are one const array; the AND/OR toggle is static markup with aria-pressed. The footer count is what makes the builder feel live even before wiring to a real endpoint.

When to use

Reach for this block on analytics, event explorer, or audit log pages where power users need multi-condition queries, wired to your events endpoint and a match count API. Connect Save as view to your views endpoint so built queries become the tabs in a saved views bar.

A natural flow around it on an Application Pro page:

Before

• Saved views tabs

After

• Data table
• Charts

What you can display

One strong use is the analytics event query builder. Other filter builders:

• Audience builder. User properties as fields with numeric operators for counts and dates.
• Alert conditions. Metric thresholds chained into a single composite trigger.
• Report filter. Dimensions and measures scoped to a single saved report.

Tip: a builder beats a search box once users can save what they build; saved conditions become the named views above your tables.
