How To Make A Power Apps Auto-Width Label

How To Make A Power Apps Auto-Width Label

An auto-width property would be useful to have for several Power Apps control types including labels and buttons etc. For example, with auto-width, we could easily create a breadcrumbs UX. Each breadcrumb is a different size and is not known in advance. In this article, I’ll give two solutions on how to make a Power Apps auto-width label. You can either build your own or download a pre-made one.

Option #1: Make Your Own Power Apps Auto-Width Label

This approach uses a clever technique to determine what the width of the label should be. We will create an HTML control with same text as the label, the same font and the same text size. Then we will rotate the text 90 degrees and set the HTML text control’s AutoHeight property to true. The height of the HTML control will tell us the length of the auto-width label.

I first saw this solution posted on Twitter by Robin Rosengrün (@power_r2) and Jake Siskon (@JakeSiskon).




Create A New Label In Canvas App

Open Power Apps studio and create a new app from blank. Insert a blank label onto the screen.



Write these words in the Text property of the label.

"The quick brown fox jumps over the lazy dog"



Also apply these properties to the new label:

Font: Font.'Open Sans'
Size: 13
PaddingBottom: 0
PaddingLeft: 0
PaddingRight: 0
PaddingTop: 0




Insert An HTML Text Control With AutoHeight Enabled

Create an HTML text control and place it on the screen.



Set the AutoHeight property of the HTML text control to true. This makes the height of the HTML control expand to fit the text inside it.

true



Apply these values to the HTML text control properties as well to ensure it uses the same formatting as the label.

Font: lbl_FlexWidthLabel.Font
Size: lbl_FlexWidthLabel.Size
PaddingBottom: 0
PaddingLeft: 0
PaddingRight: 0
PaddingTop: 0



We will use HTML and CSS code to rotate the text and make its starting position the top left corner of the control.



Copy and paste this code into the HTMLText property of the HTML text control. The code below uses Power Fx $-string notation. Ensure the label referenced between the { } brackets matches the name of the label in the app.

$"<div style='
    display: inline-block;
    margin: 0px 30px;
    position: relative;
    transform: rotate(90deg);
    transform-origin: top left;
    white-space: nowrap;
    '
>
    {lbl_FlexWidthLabel.Text}
</div>"




Set Label Width Equal To Height Of HTML Text Control

We can assume the width of the auto-width label should be equal to the height of the HTML text control.



Use this code in the Width property of the auto-width label. A reference to the padding properties of the label are also included in case we want to add extra space on the left or right.

htm_CalculateLabelWidth.Height+Self.PaddingLeft+Self.PaddingRight




Option #2: Download A Pre-Made Power Apps Auto-Width Label

In this approach, we will download and import an auto-width label component published by Microsoft. To do this, the ability to use code components in an environment must be enabled by a system administrator.




Install The Power Apps Creator Kit

Go to the Power Apps Creator Kit page on the Microsoft Learn website and download the Creator Kit.



After the Power Apps Creator Kit is downloaded, ask an administrator to check if the Power Platform environment where it will be used has the Power Apps component framework for canvas apps setting enabled. This menu where this setting is found in the Power Platform Admin Center is located at the path Environments > (Enivornment Name) > Settings > Features.



Go to make.powerapps.com and import the solution into the desired environment.



Open the solution once it has been imported. The auto-width label will appear under the custom controls group.




Import The Auto-Width Label Into A Canvas App

Open Power Apps studio and create a new canvas app from blank. Go to the Insert menu on the left-navigation bar. Scroll to the bottom of the menu and choose Get more components.



Choose the Code tab and select the Auto Width Label. Click Import.



Expand the code components group in the insert menu to reveal the Auto Width Label. Add an auto-width label to the screen.



The auto-width label needs one additional step to configure. It does not stretch to fit the text within it by default.



Set the width of the auto-width label to this code to automatically size it.

Self.AutoWidth

The CSS rotation solutions is clever but what’s missing from the guidance is where the HTML label would best be “hidden” so it can be used to calculate for the auto-width.

Would the solution work if the HTML label was set to not visible? I’m told placing it on another hidden screen is a poor choice but I’ve used this approach before for other solutions without significant overhead.

It seems the auto-width dosen’t work if you set the HTMLText control to invisible. @Jason you can try this on the x property of the HTMLText control: -Self.width.
This will keep it just to the left of the canvas and always out of view

It will be great to have an upper-bound width so that the text would not over flow it’s parent (screen or container)

min(htm_CalculateLabelWidth.Height+Self.PaddingLeft+Self.PaddingRight, Parent.Width-Self.X) //or take into account the parent's padding if any.

Thank you for this really good trick ! I added the font weight and italic option, because they count in width change.
I made a component with all these settings and I added the paddings, the alignment, and last but not least a max width. The auto width is then computed with the min between autowidth and maxwidth.

I had the same thought. Out of curosity, how’d you structure you Parameters and Properties on the component?

I figured set up a component to act as a calculator, accepting a Control as it’s input, and outputting a value for the calculated Width (as ‘AutoWidth’). This way I can place an instance of the component in the app (call it something like “FancyMath”), and then in a Control’s, such as a Label, Width property, I can place:

FancyMath.AutoWidth(Self)

Struggling to pull it together though.

Hi Matthew,

Great idea you have found and thanks for making this a nice simple guide.

Is this possible to use in a Gallery situation?

Thanks

Oh really? I had a go but couldn’t get it to work correctly. It seemed to have just kept the same with throughout the rows on the gallery.

thanks

Doesn’t seem to work in a gallery. It always keeps the width of the first calculated element.

Len(lbl_AppName.Text) * lbl_AppName.Size this worked for me
