Hello,

Indeed, the popup edit form change was not initially included in the Breaking Changes article. The information is live now. Sorry about this omission.

We know that different customers prefer different form orientations. As a first step, we reset the Grid popup form orientation to the default state, which should be better in terms of UX.

The second step is to expose properties to control the popup edit form size and orientation in UI for Blazor 3.1, which is a few weeks away.

In the meantime, you can apply the previous orientation with the following CSS code. Note that it will affect all vertical Forms inside Windows, unless you place the CSS code on a specific page only.

    .k-window-content .k-form {
        /* optional - expands the edit form */
        min-width: 400px;
    }

    .k-window-content .k-form .k-form-field {
        display: flex;
    }

    .k-window-content .k-form .k-form-field-wrap {
        max-width: calc(75% - 10px);
        flex: 1 1 auto;
    }

    .k-window-content .k-form .k-form-field > .k-form-label {
        margin-right: 10px;
        padding-top: 5px;
        width: 25%;
        text-align: end;
        flex-direction: column;
        align-items: flex-end;
        justify-content: flex-start;
    }

>> I am still unsure where we are to just ask support questions, as the feedback portal seem to force us into either choosing feature or bug. 

Yes, this portal is only for feature requests and bug reports, that is why I will mark this item as Declined. For technical assistance, use our Blazor forums or the support system.
