Tabs: Multiple tabs can be defined in a layout. Each tab can have its contents laid out using a simple grid-layout using the tab-columns and tab-rows keys.
In below example the Settings tab has a grid of 3 rows and 2 columns in which sections can be placed."layouts": [
{
"name": "default",
"tabs": [
{
"name": "settings",
"display-name": "Settings",
"layout": {
"tab-columns": "2",
"tab-rows": "3",
"sections": [ … ]
}
}]
}
]Sections: Each section is defined inside a tab and specifies its location and size inside the tab's grid-layout by using the row-index, column-index, row-span and column-span keys. Being a container itself, it can further define a grid-layout for the sub-sections it contains using the section-rows and section-columns keys.
In below example the MapReduce section occupies the first cell of the Settings tab grid, and itself has a grid-layout of 1 row and 3 columns.
"sections": [
...
{
...
"name": "section-mr-scheduler",
...
"display-name": "MapReduce",
...
"row-index": "0",
...
"column-index": "0",
...
"row-span": "1",
...
"column-span": "1",
...
"section-columns": "3",
...
"section-rows": "1",
...
"subsections": [ ... ]
...
},
...
...
]Sub-sections: Each sub-section is defined inside a section and specifies its location and size inside the section's grid-layout using the row-index, column-index, row-span and column-span keys. Each section also has an optional border boolean key which tells if a border should encapsulate its content.
...
"subsections": [
...
{
...
"name": "subsection-mr-scheduler-row1-col1",
...
"display-name": "MapReduce Framework",
...
"row-index": "0",
...
"column-index": "0",
...
"row-span": "1",
...
"column-span": "1"
...
},
...

Placement: Specifies the order of configurations that are to be placed into each sub-section. Each placement identifies a config, and which sub-section it should appear in. The placement specifies which layout it applies to using the configuration-layout key.
