Input.ChoiceSet (filtered, multiselect): Selected chips truncate text with no tooltip on hover in Teams

[mayank0505]

When using Input.ChoiceSet with isMultiSelect: true and style: "filtered", selected values render as compact pill/chip elements. For choices with longer titles, the text is heavily truncated (e.g., (ABC) Contoso Gl...), making it difficult — sometimes impossible — for users to distinguish between similar items.

There is no tooltip on hover over the chips in the Microsoft Teams desktop client, so users have no way to see the full title of a selected value.

Reproduction

Adaptive Card JSON:

{

"type": "AdaptiveCard",

"version": "1.5",

"body": [
{

"type": "Input.ChoiceSet",

"id": "products",

"isMultiSelect": true,

"style": "filtered",

"choices": [

{ "title": "(ABC) Contoso Global Equity Fund Class A", "value": "1" },

{ "title": "(ABCX) Contoso Global Equity Fund Class Z", "value": "2" },

{ "title": "(DEF) Contoso Dynamic Allocation Fund Class A", "value": "3" },

{ "title": "(DEFX) Contoso Dynamic Allocation Fund Class Z", "value": "4" },

{ "title": "(GHI) Contoso Recovery Fund Class A", "value": "5" }

],

"value": "1,2,3,4,5"

}

  "actions": [{ "type": "Action.Submit", "title": "Submit" }]

}

**Steps**:

1. Render the above card in Microsoft Teams

2. Observe the selected chips — titles are truncated

3. Hover over any chip — no tooltip appears

**Expected behaviour**

- **Minimum**: A tooltip should appear on hover showing the full title text of the selected choice

- Ideal: Provide a property to control chip rendering, such as:

- > chipLayout: "wrap" — display chips on separate rows with full/longer text

- > maxHeight on the chip container — allow vertical scrolling when many items are selected

- > Or increase the default width allocated to each chip

**Actual behaviour**

- Chips truncate text after ~12-15 characters with ellipsis

- No tooltip on hover

- Users cannot distinguish between similarly named items (e.g., multiple fund classes with the same prefix)

**Environment**

- Host app: Microsoft Teams Web client and Windows desktop app

- Adaptive Card schema version: 1.5

- Card context: Bot-sent Adaptive Card with msteams.width: "Full"

**Impact**

This is a significant usability issue for enterprise scenarios where choice titles contain product codes, long identifiers, or hierarchical names. Users are forced to guess which truncated chip represents which item, leading to errors.

**Suggested solutions**

- Add tooltip on hover — lowest effort, highest impact

- Add a chipStyle or chipLayout property — gives card authors control over chip display

- Increase default chip width or allow chips to wrap to a second line showing more text
