Mat-Stepper-将特定步骤更改为仅点 [英] Mat-Stepper - change specific steps to just dots

问题描述

我看过这篇有关如何删除标题的帖子 删除Material Stepper标头

I've seen this post on how to remove the header Remove the Material Stepper header

但是我要在特定步骤上执行的操作是在显示该数字的跨度上不显示任何内容.

But all I want on specific steps is to display none on span showing the number.

隐藏步进器的内部:

<span class="mat-step-icon-content ng-star-inserted">1</span>

我尝试使用id和.span:after或仅显示.span而不显示任何内容，但没有运气.

I tried with id and .span:after or just .span with display none, but no luck..

#importer > .span{
  display:none;
}

这是可行的，但我不希望它一起消失.

This one works but I don't want it to disappear all together.. just the number and just on specific steps..

::ng-deep #importer > .mat-horizontal-stepper-header-container {
  display: none !important;
}

问题:

1)步进器的响应能力；

2)正确的样式仅在经过特定的步进步骤之后

推荐答案

您将无法通过使用类来做到这一点，因此它将无法实现动态变化.如果这不是问题，那么我建议使用SASS mixin创建每个标题项所需的样式.示例:

You won't be able to do this by using classes so it will not be able to be dynamic. If this is not a problem then I would recommend using a SASS mixin to create the styles you will need for each header item. Example:

@mixin hide-option($index, $label: '') {
  mat-step-header:nth-of-type(#{$index}) {
    .mat-step-icon-not-touched span,
    .mat-step-icon span,
    .mat-step-icon-not-touched .mat-icon,
    .mat-step-icon .mat-icon {
      display: none;
    }

    @if ($label == '') {
      .mat-step-icon {
        height: 5px;
        width: 5px;
      }
    }

    .mat-step-icon-not-touched:after,
    .mat-step-icon:after {
      content: $label;
      position: absolute;
      left: 8px;
      top: 3px;
    }
  }
}

:host /deep/ {

  mat-step-header .mat-step-label {
      overflow: visible;
  }

  @include hide-option(1, '1');
  @include hide-option(2);
  @include hide-option(3);
  @include hide-option(4);
  @include hide-option(5, '2');
  @include hide-option(6);
  @include hide-option(7);
  @include hide-option(8);
  @include hide-option(9, '3');
  @include hide-option(10, '4');
  @include hide-option(11);
  @include hide-option(12, '5');
  @include hide-option(13, '6');
}
