Collapse / Expand icons

[Martin Pamplin]

I have been asked if we can change the icons used to expand & collapse the columns & swim lanes in a kanban board. I can see that these are derived from the ej.widgets charater set.

I am hoping that someone may have done this before and can give me an example.

Hi Martin, 

 

We have achieved your requirement through CSS and default EJ icons, kindly refer the below links.

.e-kanban .e-slcollapse:before, 

  .e-kanban .e-clcollapse:before { 

      content: "\e606"; 

    } 

    .e-kanban .e-slexpand:before, 

    .e-kanban .e-clexpand:before { 

      content: "\e607" 

    }

Thanks, I have that working. The question is can I add my own icons in here somehow?

Hi Martin, 

 

Yes, custom icon can be added in the same way. In the below sample, Bootstrap Glyphicon is added.

<link rel="stylesheet" rel='nofollow' href="//maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">  

 

<style>  

  .e-kanban .e-slcollapse:before, 

  .e-kanban .e-clcollapse:before { 

     content: "\e030"; 

    } 

    .e-kanban .e-slexpand:before, 

    .e-kanban .e-clexpand:before { 

      content: "\e031" 

    } 

  </style> 

 

create: function (args){ 

                   var lenCl = $(".e-icon.e-clexpand").length; 

                                  for(var i=0; i<lenCl; i++) { 

                                                               icon = $(".e-icon.e-clexpand")[0]; 

                                                               icon.classList.replace("e-icon", "glyphicon"); 

                                               } 

                                               var lenSwim = $(".e-icon.e-slexpand").length; 

                                               for(var j=0; j<lenSwim; j++) { 

                                                               icon = $(".e-icon.e-slexpand")[0]; 

                                                               icon.classList.replace("e-icon", "glyphicon"); 

                                               } 

                  }

Yes, but I am asking if we can create an entirely new, never seen before, icon?

Hi Martin, 

 

Yes, you can create your own font icons, for which many online tools are available to make use of. The generated icons can then be located and referenced in your application which uses ej controls, by defining its source path to the font-face as shown in the following code example. Once the font family is defined in your application, you can now replace any of the existing icon content with the newly generated content code. 

  

@font-face { 

    font-family: 'customiconpackname'; 

    src: url('../fonts/customiconpack.eot?lchn8y'); 

    src: url('../fonts/customiconpack.eot?lchn8y#iefix') format('embedded-opentype'), 

         url('../fonts/customiconpack.ttf?lchn8y') format('truetype'), 

         url('../fonts/customiconpack.woff2?lchn8y') format('woff'), 

         url('../fonts/customiconpack.woff?lchn8y') format('woff'), 

         url('../fonts/customiconpack.svg?lchn8y#customiconpack') format('svg'); 

    font-weight: normal; 

    font-style: normal; 

} 

 

selector:after { 

    font-family: 'customiconpackname'; 

    content: '\e953'; 

    } 

 

Please refer the following stack over flow link which will demonstrate how to generate custom icons and use it in application
