extjs - how to wrap text of selectfield option in sencha touch 2 -


i'am trying display sencha touch 2 selectfield long option text text gets truncated ellipsis, very long option t....

how display couple lines in 1 option?

code:

{ xtype: 'selectfield', options:[     {        text: 'very long option wish splint 2 separate lines',        value: 0      },     {        text: 'another long option wish splint 2 separate lines',         value: 1     }  ] }

i've tried using \n , <br/> not working.

there 3 2 ways this.

  1. use labelwrap config option set true. avoid truncating text appears on selectfield initially. later when tap on selectfield; you've 2 choices. using picker or list. picker used if set true in usepicker config. if on tablet, desktop or mobile default list shown containing options. using labelwrap config not usefull if options displayed in list after tap on selectfield.

  2. use following css override avoid truncating.

    .x-list-item-label{     height: 100% !important;  }  .x-list-label{     white-space: pre-wrap !important;  }

    this override along above mentioned labelwrap config set true make both list , selectfield display whole text neatly. override styles may affect appearance of other lists in app.

  3. third approach can override ext.field.select , create custom select field. in style, need override following method - gettabletpicker generated list displayed on tap of selectfield. code st source fallows - 

    gettabletpicker: function() { var config = this.getdefaulttabletpickerconfig();  if (!this.listpanel) {     this.listpanel = ext.create('ext.panel', ext.apply({         centered: true,         modal: true,         cls: ext.basecssprefix + 'select-overlay',         layout: 'fit',         hideonmasktap: true,         items: {             xtype: 'list',             store: this.getstore(),             itemtpl: '<span class="x-list-label">{' + this.getdisplayfield() + ':htmlencode}</span>',             listeners: {                 select : this.onlistselect,                 itemtap: this.onlisttap,                 scope  :             }         }     }, config)); }  return this.listpanel; }

    check out line itemtpl , cls config. here both options set styles defined list. these decide appearance of list displayed on tap of selectfield. approach might sound dirty. it's useful, if want make drastic changes in appearance , behaviour.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
