iFrame Not Expanding to Full Screen in Creatio Tab

Hi Creatio Community,

I'm integrating an iFrame into a Creatio tab for our Custom App. The integration works, but the iFrame does not expand to full screen inside the tab.

My Current Setup

I’m inserting the usr.FrameComponent inside a TabContainer, but it doesn’t fill the entire available space.

viewConfigDiff: /**SCHEMA_VIEW_CONFIG_DIFF*/[
...,
           {
				"operation": "insert",
				"name": "GridContainer_Sales",
				"values": {
					"type": "crt.GridContainer",
					"items": [],
					"rows": "minmax(32px, max-content)",
					"columns": [
						"minmax(32px, 1fr)"
					],
					"gap": {
						"columnGap": "large",
						"rowGap": "none"
					},
					"visible": true,
					"color": "transparent",
					"borderRadius": "none",
					"padding": {
						"top": "none",
						"right": "none",
						"bottom": "none",
						"left": "none"
					},
					"alignItems": "stretch"
				},
				"parentName": "TabContainer_Sales",
				"propertyName": "items",
				"index": 0
			},
            {
				"operation": "insert",
				"name": "Label_mmxxxre",
				"values": {
					"layoutConfig": {
						"column": 1,
						"row": 1,
						"colSpan": 1,
						"rowSpan": 18
					},
					"type": "usr.FrameComponent",
		         "src": "https://www.smarten.com"
				},
				"parentName": "GridContainer_Sales",
				"propertyName": "items",
				"index": 0
			},
			...

Issue

Even when I try using fitContent: true or modifying layoutConfig, the iFrame remains small and doesn’t adjust to the full tab size.

What I Tried

• Setting fitContent: true for the TabContainer and GridContainer.
• Adjusting layoutConfig with rowSpan: 18.
• Setting explicit height: 100% and width: 100%.

Has anyone encountered this issue? How can I make the iFrame take up the entire available space in the tab?

Thanks in advance for any help!
