问题
My treecolumn has a ComboBox as the editor component. The choices in the options menu are rendered correctly with HTML, but the input box does not render HTML, it only shows the tags (See images below.)
How I can make it to also render the value as HTML?
P.S. This solution here EXTJS 4 render HTML of a selected value in a combobox is seems like not working with extjs6 version, check here
Here's the problem place code (rendere in case depth.TypeParameter: returns text with html tags)
{
xtype: 'treecolumn',
dataIndex: 'text',
text: Poly.utils.locale.Base.localeName,
flex: 1,
getEditor: function (record) {
return me.getController().getEditor(record);
},
renderer: function (value, meta, record) {
var depth = Poly.view.fluidProperties.sample.Tree.depth;
switch (record.getDepth()) {
case depth.Temperature:
if (Ext.isEmpty(record.get('temperature'))) {
return value;
}
var text = Ext.String.format('T = {0} {1}',
record.get('temperature').toFixed(2),
Poly.utils.UniSum.GetUnit(me.getViewModel().get('temperatureUnitId')).name);
return text;
case depth.TypeParameter:
if (record.get('isNew')) {
return value;
}
return Poly.enums.TypeFluidParameter.getName(record.get('fluidParameter'), record.parentNode.get('typeFluid'), true);
}
return value;
}
}

Html input element can't display HTML, so you need to change template add div. Div can be shown as an overlay over input.
Best way to achieve this is by extending ComboBox:
Ext.define('HtmlComboBox', {
extend: 'Ext.form.field.ComboBox',
fieldSubTpl: [ // note: {id} here is really {inputId}, but {cmpId} is available
'<input id="{id}" data-ref="inputEl" type="{type}" {inputAttrTpl}',
' size="1"', // allows inputs to fully respect CSS widths across all browsers
'<tpl if="name"> name="{name}"</tpl>',
'<tpl if="value"> value="{[Ext.util.Format.htmlEncode(values.value)]}"</tpl>',
'<tpl if="placeholder"> placeholder="{placeholder}"</tpl>',
'{%if (values.maxLength !== undefined){%} maxlength="{maxLength}"{%}%}',
'<tpl if="readOnly"> readonly="readonly"</tpl>',
'<tpl if="disabled"> disabled="disabled"</tpl>',
'<tpl if="tabIdx != null"> tabindex="{tabIdx}"</tpl>',
'<tpl if="fieldStyle"> style="{fieldStyle}"</tpl>',
'<tpl foreach="inputElAriaAttributes"> {$}="{.}"</tpl>',
' class="{fieldCls} {typeCls} {typeCls}-{ui} {editableCls} {inputCls}" autocomplete="off"/>',
// overlay element to show formatted value
'<div id="{cmpId}-overlayEl" data-ref="overlayEl"<tpl if="name"> name="{name}-overlayEl"</tpl> class="{fieldCls}-overlay {typeCls} {typeCls}-{ui} {inputCls}">{value}</div>',
{
disableFormats: true
}
],
forceSelection: true,
childEls: [
'overlayEl'
],
setRawValue: function(value) {
var me = this;
// set value in overlay
if (me.rendered) {
me.overlayEl.update(value);
}
return me.callParent([value]);
}
});
With that, some additional CSS is required:
.x-form-text-wrap {
position: relative;
}
.x-form-field-overlay {
background-color: #ffffff;
position: absolute;
top: 0;
}

I suppose that your editor is combo, by default combo (as well as many other components) display HTML as plain text.
Example
I guess as workaround you could overrite combo (or any other component), i.e. change component <input> element to <div>. It will entail overrites of some methods (setValue() for example).
