Perspective Text Field: Single-Line, Not Wrappable

Text in a Perspective Text Field stays on one line because the component uses an HTML <input type="text">, which does not provide multiline wrapping. Changing wordWrap to normal or break-word cannot convert that control into a multiline editor. Use a Text Area for editable wrapped text, or a Label when the text is display-only.

How should you read the wrapping symptom?

Look at the rendered behavior before changing styles. If a Text Field remains single-line while a Label wraps in the same Flex View, the layout can already allocate wrapped content; the component type is the limiting element. A style that works on the Label but not the Text Field is another strong discriminator.

Separate wrapping from clipping and sizing. A narrow Text Field can hide part of a long value, scroll its visible text horizontally, or display only the section around the caret. Those are consequences of fitting a single-line editor into limited width, not failed multiline layout.

Why does wordWrap not change the Text Field?

The signal chain starts with a string, passes it to the Perspective component, and ends at the browser control. The Text Field sends that string to an HTML text input. The browser supplies the editing behavior for that input, including caret movement, selection, keyboard handling, and its single-line presentation.

CSS wrapping rules operate only where the rendered element supports line layout. They can determine how a text block breaks at spaces or within long words, but they do not change a single-line input into a multiline control. The values normal and break-word therefore cannot produce the requested result on this component.

The successful Label test follows the same mechanism. A Label displays text rather than editing it through a single-line input, so its rendered text can occupy multiple lines. A Text Area provides the appropriate editable multiline behavior. Tuning margins, flex growth, font size, or wrapping styles does not fix a component-selection mismatch.

Which component should replace the Text Field?

Choose from the required operator action, not from the desired appearance. Use a Text Field when the operator enters a short, single-line value. Use a Text Area when the operator must enter or edit content that may span multiple lines. Use a Label when the operator only needs to read wrapped text.

A Label placed beneath another component can imitate a second visual line, but it is not a wrapped Text Field. That workaround divides one logical value across separate display elements, complicates bindings, and does not give the operator a single multiline editing surface. It is reasonable only when the content is display-only and the layout intentionally presents separate fields.

Before replacing the component, inspect the value path. Identify the binding or input handler that supplies the current Text Field, any transformations applied to it, and any downstream action that consumes edits. The replacement must preserve those behaviors as well as the visible text.

How do you implement the multiline fix?

1. Record the current Text Field binding, event handling, validation behavior, security restrictions, and layout settings. Test the live value first so a data-path fault is not mistaken for a display fault.
2. Decide whether the text is editable. Select a Text Area for editable multiline content or a Label for display-only content.
3. Place the replacement in the same Flex View and give it enough width and height for the intended number of visible lines. Wrapping determines line breaks; the parent layout still determines how much of the result is visible.
4. Reconnect the original value source and any required write path. Preserve transformations and validation that belong to the application rather than the old component.
5. Apply the shared style to the replacement, then review individual style declarations. Remove reliance on wordWrap as a remedy for the original Text Field because that declaration never changed its control type.
6. Retest focus, editing, submission, and navigation behavior. A Text Area is multiline by design, so confirm that its operator interaction matches the process requirement.
7. Remove the old Text Field only after the replacement passes both read and write tests.

How do you verify the correction?

Use test strings that exercise different failure modes: several words separated by spaces, one uninterrupted long token, and content longer than the visible area. Confirm that ordinary text moves onto another line in the replacement and remains one logical value. Check that the Flex View does not collapse the component height or conceal the additional lines.

For editable text, enter a value, move focus away, return to the view, and verify that the same content is read back from its real data source. Confirm any configured validation and downstream action receives the complete string. For a Label, change the bound value at its source and verify that the displayed lines update without maintaining a duplicate manual value.

Finally, compare the replacement at the narrowest supported view size. A desktop-width test can conceal a layout constraint that reappears on a smaller client. The fix is complete only when both wrapping and the value path work under the intended Flex View sizing.

Which pitfalls recur with this symptom?

The most common mistake is continuing to adjust wordWrap after the component boundary is known. Another is adding height to the Text Field and expecting the browser to create another editable line. Neither action changes the underlying single-line input.

Do not treat a two-Label arrangement as equivalent to multiline entry. It can reproduce an appearance but not the editing, selection, validation, or binding behavior of one multiline value. Also keep font-family selection separate from wrapping diagnosis: the absence of a font dropdown does not explain why the Text Field remains single-line.

Measure before adjusting. Confirm the incoming value, available layout space, and rendered component type in that order. Styling cannot repair an incorrect binding, and tuning does not change a single-line editor into a multiline one.
