Chapter 55. Page authoring
Pages are collections of following components:
- Core components
- Navigational components
- Reporting components
- Heatmaps
Also, a page can have none or any number of components. The Page Editor tool is used to edit the pages.
A page has either the Fluid style or the Page style. The Fluid style is a classical web page with a vertical scroll bar, when the page exceeds the available height. The Page style is a web page that will always fit to the windows height.
55.1. Creating pages
You can use the Pages perspective to create a page that consists of different types of components. After a page has been created and all the components in it defined, use the Page Editor to save, delete, rename, or copy pages as required.

.
The external component location is set and configured with the dashbuilder.components.dir
system property. The default value of this system property is /tmp/dashbuilder/components
. You must set the component under the components directory with a parent directory, which is used as the component ID. For example, if the component ID is mycomp
and the component directory is /tmp/dashbuilder/components
, then the component base directory is /tmp/dashbuilder/components/mycomp
.
Business Central checks the manifest.json
file in the components directory. The manifest.json
must contain at least one name
text parameter.
Parameter | Description |
---|---|
| Name of the component displayed under Components section. |
| Icon of the component displayed under Components section. |
