Configure which categories your app supports in the runtime options:

```ts
import { getOrCreateConsentRuntime } from 'c15t';

const { consentStore } = getOrCreateConsentRuntime({
  mode: 'hosted',
  backendURL: 'https://your-instance.c15t.dev',
  consentCategories: ['necessary', 'measurement', 'marketing'],
});
```

<import src="../../../shared/concepts/consent-categories.mdx#categories-table" />

Check if a specific category has consent using the `has()` method:

```ts
const state = consentStore.getState();

if (state.has('measurement')) {
  // Safe to load analytics scripts
}

// Complex conditions
if (state.has({ and: ['measurement', 'marketing'] })) {
  // Both measurement and marketing are granted
}
```

<import src="../../../shared/concepts/consent-categories.mdx#configuration" />

You can dynamically update which categories are active:

```ts
const state = consentStore.getState();

// Add a new category
state.setConsentCategories([...state.consentCategories, 'experience']);
```
