# SmartComboBoxAdapter

## Overview

The adapter enhances the auto-complete functionality of the `Wisej.Web.ComboBox` control by integrating semantic filtering capabilities. This advanced mechanism employs semantic embeddings to improve the accuracy and relevance of suggested items, ensuring a more intuitive user experience.

It utilizes the HuggingFace TransformersJs library (through the [HuggingFaceJavaScriptEndpoint](/ai/components/api/smartendpoint/wisej.ai.endpoints.huggingfacejavascriptendpoint.md))  to generate semantic embeddings in-browser, providing fast and relevant suggestions without the latency or privacy concerns associated with transmitting data to a server.

## Configuration

```csharp
[Extends(typeof(ComboBox), allowMultiple: true)]
[WorksWith(typeof(HuggingFaceJavaScriptEndpoint))]
```

## Properties

In addition to the properties inherited from the [SmartAdapter](/ai/components/adapters/smartadapter.md), the SmartCoSmartComboBoxAdapter exposes the following additional properties.

### Model

Embedding model used by the HuggingFace Transformerjs library running in the browser.

See <https://huggingface.co/docs/transformers.js/en/index> for available models.

Default is "Xenova/all-MiniLM-L6-v2";

## Extender Properties

### Similarity

Similarity level threshold needed for an item to qualify, ranging from 0.1 to 1.0 (1 means identical).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wisej.com/ai/components/adapters/smartcomboboxadapter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
