feat(stepper): Support additional properties for step #6509

g1shin · 2017-08-16T21:22:37Z

Add support for editable, optional, and completed properties of each step.

g1shin · 2017-08-16T21:23:42Z

I had to close and reopen the PR for additional properties of step b/c of rebase issues 😢
Previous comments addressed; ready for review.

nit: can just do optional="true"

also, can you add a optional horizontal step

Or just optional with no expression

Hmm I wonder if this is something we want to give the user control of by making it an @Input()?

@jelbourn WDYT of something like this:

@Input() get completed() { return this._customCompleted == null ? this._defaultCompleted : this._customCompleted; } set completed(value) { this._customCompleted = value == null ? null : coerceBooleanProperty(value); } private _customCompleted: boolean | null = null; private get _defaultCompleted() { return this._stepControl ? this._stepControl.valid && this.interacted : this.interacted; }

This way most users could use the default completeness behavior, but they could still override if they want

Seems reasonable, though _defaultCompleted would be a function

This makes sense if you're thinking about the step being invalid due to a required field not being filled out, but it makes less sense if you consider invalid for other reasons (e.g. entering "1234" as your email).

Need to think more about what the right behavior for optional is...

@mmalerba Do you mean that if the step is optional but the field is invalid due to some other reason, the user shouldn't be able to move on? If it is optional, shouldn't the user be able to move on even if the input is not valid? The field will still fire an error, so the user will still be aware that the input is invalid as they move on.

I think if its optional they should be able to skip it, not enter invalid input

<div class="mat-step-indicator" [ngSwitch]="_indicatorType"> <span *ngSwitchCase="number">{{i + 1}}</span> <md-icon *ngSwitchCase="check">done</md-icon> <md-icon *ngSwitchCase="edit">create</md-icon> </div>

Could we share this icon group between stepper vertical and stepper horizontal?

@kara Sorry, what do you mean by sharing the icon group? Do you mean like creating a separate icon group component with the template?

Yeah, I meant an internal directive for the shared functionality. If they have a lot in common, would be easier to update together.

Ready for review again. I also left some follow-up comments 👍

could we not just combine these 2 internal components (and their parent div) into a single md-step-header component?

How about just one @Input() with type MdStepLabel | string, internally you can then have getters to use in your template:

get _stringLabel(): string | null { return this.label instanceof MdStepLabel ? null : this.label; } get _templateLabel(): MdStepLabel | null { return this.label instanceof MdStepLabel ? this.label : null; }

+export class MdStepHeader {
+  /** Unique label ID of step header. */

+  labelId: string;


rather than having these as inputs you can just do it in the parent template:

<mat-step-header [id]="_getLabelId(i)" [attr.aria-controls]="_getContentId(i)" ...></mat-step-header>

+  <div class="mat-stepper-header" #stepperHeader (click)="step.select()"


you can remove this div and get access to the md-step-header element like this:

@ViewChildren(MdStepHeader, {read: ElementRef}) _stepHeaders;

(and same for horizontal)
