Layout Grid
Introduction
The layout grid is a widget that gives structure to your pages.
A layout grid consists of rows and columns:
In a browser, the layout grid is based on the Bootstrap grid system. For more information on the Bootstrap grid system, see the official Bootstrap documentation.
Row and column properties described below are available if your app has Atlas Core version 3.0 or above.
For more information on row and column properties, see the Rows and Their Properties and Columns and Their Properties sections.
Layout Grid Properties
An example of layout grid properties is represented in the image below:
Layout grid properties consist of the following sections:
Common Section
Design Properties Section
General Section
Width
The General section contains the Width property, which determines the width of the layout grid.
| Value | Description |
|---|---|
| Full width | The layout grid spans the full width of the available space and will stretch and shrink. |
| Fixed width | The layout grid has a fixed width but it is still responsive to viewport changes. Note that the width is not configurable in Studio Pro but is determined by Bootstrap. |
Visibility Section
Visibility determines whether a widget is displayed to the end-user as part of the page.
For more information on properties of this section, see the Visibility Section section in Properties Common in the Page Editor.
Rows and Their Properties
A layout grid can contain one or more rows. Each row contains columns and the number of columns can differ per row.

- Top – columns are aligned to the top of the layout grid
- Center – columns are aligned to the center of the layout grid
- Bottom – columns are aligned to the bottom of the layout grid
- Spacing between columns – when set to Yes, adds spacing between columns

Visibility determines whether a widget is displayed to the end-user as part of the page.
For more information on properties of this section, see the Visibility Section section in Properties Common in the Page Editor.
Columns and Their Properties
Columns form a row of a layout grid.
An example of layout grid column properties is represented in the image below:
Layout grid column properties consist of the following sections:
Common Section
General Section
Width
This property allows you to define the column width.
For web pages, it is divided into Desktop Width, Tablet Width,and Phone Width which allows you to define column width per device type.
For native pages, you will see one property called Width.
The Width property contains the following options:
- Auto-fill – takes the available space for a column (for example, if there is one column, it will span the column for the whole row, and for two columns, it will divide the space equally between them)
- Auto-fit content – automatically fits the size of the column to its content
- Manual – allows you to manually set the size of the columns
Column width can be used to make your layout more flexible and adaptive to different types of devices.
For example, you have a layout grid with one row and two columns: a picture is in one column, and a text with details is in another.
For the desktop and tablet, you might want to set the first column with a picture to Auto-fit content and the second one to Auto-fill, this way the first column will adjust to the size of the picture, while the second one will take the rest of the row:
For phone, it can be a good idea to place two columns one under another, setting them to Manual width of 12 (for more information on the column size property, see the Size section). In this case, the second column will be automatically wrapped to another line:
On the picture below you can see the settings for two column described above:
Size
The Size option is displayed only if the width is set to Manual.
This setting allows you to manually set the column size for desktop, tablet, or phone by using the corresponding property: Desktop Size, Tablet Size, Phone Size.
Align Vertically
The Align vertically property overrides the Align columns vertically property on the row and sets alignment for an individual column.
