+# Making Dynamic Dataview Queries via Meta Bind
+A practical example showing how to dynamically populate MetaBind input fields using Dataview queries. This addresses the common use case of wanting to filter suggester options based on note properties, in ways that isn't possible with normal optionQuery. Will require adjustment based on your particular use case, but it's a place to start.
+
+The code block here is the equivalent of making the query `WHERE {property} = "{value}"` 
+
+```js-engine
+const dv = engine.getPlugin('dataview').api;
+
+const property = "categories";   // frontmatter property to filter on
+const value    = "character";    // value to match
+// Equivalent to the Dataview query WHERE categories = "character"
+
+// Query notes where the property contains the value
+const pages = dv.pages()
+  .where(p => p[property] && p[property].includes(value));
+
+// Turn into Meta Bind options
+const options = pages.map(p => `option(${p.file.name})`).join(", ");
+
+// Build the Meta Bind input string
+const inputField = `\`INPUT[listSuggester(${options}):${value}]\``;
+
+return engine.markdown.create(inputField);
+```
