Grouping records in the timeline view is similar to grouping records in grid or gantt views with some important differences explained below. ## Understanding timeline view grouping - The **Group** option can be found near the middle of the view customization bar. - Once clicked, several configuration options will appear. These options are covered in the [Guide to grouped records](/docs/guide-to-grouped-records) article. It’s important to remember that if you already have a view with groups set up the way you’d like them to appear in the Timeline view, then you can click “Copy from another view” to save yourself a bit of time. - If a timeline view is grouped by a field that allows multiple values, then the [Utilization function](/docs/timeline-view-resource-allocation) **will be unavailable**. ## Showing group overviews in timeline summaries Choosing to summarize groups as an overview in timeline views allows end users to view high-level details about the records associated with one or more of the groups that you have set up in the timeline view. The group overview summary will show: - The name of the group being summarized - The date range of records within the group - The number of records in the group ## Configuring and using group overviews in timeline summaries 1. Navigate to the base and table containing the view where you want to show a group overview summary. You’ll need to have already [set up one or more groups within the view](/docs/timeline-view-grouping#understanding-timeline-view-grouping). Alternatively, set those up now before proceeding. 2. Next, click on the **Summarize** option in the view. Here, you will choose the **Group overview** summary option and then choose which groups will show the group overview summary. - Note that the location choices will be restricted to the groups that you’ve already configured. - If you aren’t seeing an expected group, then go back to the group settings and add or modify those settings so that the group appears in the view. - You can enable just one, a mix of, or all of the groups in the timeline view to show the group overview summary. ![](https://cdn.airtable.document360.io/d0ee2ee4-3f78-47c7-b388-85e40be9fb89/Images/Documentation/Screenshot 2024-05-13 at 1.27.41 PM.png) 3. Now, users can expand and collapse groups to hide and reveal these group overview summaries. ![](https://cdn.airtable.document360.io/d0ee2ee4-3f78-47c7-b388-85e40be9fb89/Images/Documentation/timeline_group_overview_summaries_2024(2).png) ## Using drag-drop groupings - One of the main differences between grid/gantt views and the timeline view’s groupings is the ability to drag and drop timeline records into different groupings. - When the value that the record is being grouped by is connected to a single value field such as a Single select field or a Linked record field with “Allow linking to multiple records” turned off, dragging a record from one group to another will result in the removal of original value and the new group’s value will be added. Here’s an example of that process in action: ![viewsTimelineGroupedMove04112022](https://cdn.airtable.document360.io/d0ee2ee4-3f78-47c7-b388-85e40be9fb89/Images/Documentation/viewsTimelineGroupedMove04112022.gif) Notice that the green-colored “Technology Design” grouping is removed from the view once we move the record to another grouping. This is because no other records in our view currently meet the [filter conditions](/docs/guide-to-filtering-records-using-conditions). ## Grouping behavior with multiple options In grid and Gantt views, when a grouping has multiple values it creates a new “pseudo” grouping that is composed of those multiple values. In a Timeline view, you can decide whether the same records split into multiple groups or if it only appears as the single “pseudo” group. - If you toggle the “Split multiple values into individual groups” option on, then the same record will appear in each group that it is associated with. ![viewsTimelineGroupMulti04112022](https://cdn.airtable.document360.io/d0ee2ee4-3f78-47c7-b388-85e40be9fb89/Images/Documentation/viewsTimelineGroupMulti04112022.jpeg) - However, if you choose to leave that option toggled off, then the record will appear in the “pseudo” grouping that is a combination of all of the groups it is a part of. ![viewsTImelineGroupSplitValuesToggle04112022](https://cdn.airtable.document360.io/d0ee2ee4-3f78-47c7-b388-85e40be9fb89/Images/Documentation/viewsTImelineGroupSplitValuesToggle04112022.gif) - When you drag-drop an event into the multiple-valued grouping it will remove all of its current group attributes and have the multiple matching group values added instead. If you move a multi-grouped event to a single group it will remove all the group values and replace those with the single group value. - The important thing to be aware of here is that **groups are not appended when you drag-drop events**. Instead, they are removed and then made to match the attributes of the group where the event was dragged to.![viewsTimelineGroupMoveRecords04112022](https://cdn.airtable.document360.io/d0ee2ee4-3f78-47c7-b388-85e40be9fb89/Images/Documentation/viewsTimelineGroupMoveRecords04112022.gif) > [!CAUTION] > Note > > Even though records may appear multiple times when the “Split multiple values into individual groups” option is on, **they will still only be counted once** in Timeline view’s summary bar and other Airtable functions/formulas. ## FAQs **I don't see the option to split multiple values into individual groups, what might the reason be for this?** In order to see this option, the field you are grouping records by will need to be a [Multiple select field](/docs/multiple-select-field).
